Miley has been spotted wearing a diamond ring on that finger, but previously laughed off engagement rumors. Today she released a statement saying, "I'm so happy to be engaged and look forward to a life of happiness with Liam."

This twosome have been dating for three years, and they seem really happy together. But we've heard a lot of chatter about their ages (Miley is 19; Liam is 22), with some people saying they're too young to be making such a big life decision.

What do you guys think? Is 19 too young to get married, or does love have no age requirement?
